Abstract (en)
[origin: WO2012092626A1] A process for treating a polymer having a hydrolyzable functionality, the method comprising: (i.) providing a polymer having hydrolyzable functionality; and (ii.) introducing a stabilizing agent to the polymer, where the stabilizing agent is defined by the formula (I) where ÷ is a hydrolyzable group that forms an acidic species upon hydrolysis, where R2, R3, and R4 are each independently a halogen atom, a hydrocarbyl group, a hydrocarboxylate group, or a hydrocarbyloxy group.
